I'm very pleased to have chosen Dr. Mamnoon as my primary doctor. He addresses each and every concern I may have with any health issues. He makes me feel comfortable and at ease during my visits and answers all my medical questions with easy to understand terminology. Thankyou Dr. Mamnoon Fred&Diane Lojacono 5/16/2017

Run! Do not come here. Highly incompetent office. All the stupid problems I had I could type for hours. What Dr not once but twice prescribed an antibiotic without seeing me the first time, then a week later knowing how sick I was for so long tells me I'm pretty certain it's vital but take this antibodic for three weeks. Never looked at me or touched me Last I knew if it's vital they won't help. Morons. So many times had to call three and four times to get a simple answer. I could go.on Run!
My apologies for your poor experience at my office. I would like an opportunity to discuss the challenges you faced so that i can make improvements. sincerely, sameer mamnoon

After making my appointing through Zocdoc, AND speaking to this doctors office staff directly on the phone to confirm my appointment, AND receiving confirmation by email about this appointment, AND receiving another reminder the day prior to my appointment... I was called by "Sandy" at the office of Dr. Sameer Mamnoon MD on the MORNING OF MY APPOINTMENT and was told she cancelled my Appointment as Zocdoc Patents are not priority!!!! She then hung up on me when I asked for an explanation!
My apologies for your poor experience at my office. I would like an opportunity to discuss the challenges you faced so that i can make improvements. sincerely, sameer mamnoon
